The automobile is one of the most important inventions in the last five hundreds years. We have more freedom because of the coming of automobile,and  it makes our lives more convenient and gives us more fun.Personally speaking ,the automobile has changed modern life.  Firstly,From other countries to the place ten kilometers away from home,cars make our world smaller and smaller.We can take a car to go shopping or to have a picnic in forest.,with driving car,we can go anywhere we want to have a trip.Moreover,cars give us lots of fun.My favorite race is F1.It is so exciting and full of enthusiasm that always catches my eye. Cars are also a kind of art.Many companies design various cars with different color and shape to make them  be fantastic and absorbing.Many people love collecting a variety of model cars which gives them happy and satisfy.  Secondly,as for economy,the car gives an impetus to economic growth.Many industries have been built to produce cars and it has provided rich jobs for social.Many people got a job to make a living thus it make our social more harmony.Meanwhile,cars also foster the advancement of science and technique.A large number of students major in some subjects relate to automobile and automation in the university.That suggests that cars has became a part of our lives.  Admittedly,cars bring some troubles,such as,air pollution,noisy pollution and accident.The more cars means the more gas will be produced by cars that has an bad impact on environment and people.Many plants will be killed and many people gain lung disease.Besides,people often do not abide traffic law,for example, running a red light,drunken driving,that is a huge threaten to safety of person.However,in my opinion,these problems can be solved easily as long as we design some new cars that use other energy such as sun energy instead of fossil fuel,and enhance safety awareness of people. The car is essential for our modern lives.The future of car will be more lighter.  To conclude,the car is playing an more and more crucial role in modern society.
